When installing the positioning rod, the movable frame contacts the inner wall of the connecting groove, and the movable frame moves under force, compressing the movable spring. The movement of the movable frame drives the fixed ring to move, and the fixed ring clamps and fixes one end of the spring steel. When the connecting block moves out of the connecting groove, the fixed ring resets, thereby automatically unfixing one end of the spring steel. This facilitates the automatic fixing and unfixing of one end of the spring steel during the installation and disassembly of the positioning rod. At the same time, when the motor drives the positioning rod to rotate, the guide rod rotates and drives the guide seat to move, so that the spring steel is automatically and evenly wound on the positioning rod.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-6 In this embodiment of the invention, the manufacturing process of the mattress core spring includes the following steps:

[0029] Step 1: Using a winding device, connect one end of the spring steel to the rod;

[0030] Step 2: Install the rod onto the winding equipment. During this process, the rod and one end of the spring steel are automatically fixed, and the spring steel is wound onto the rod using the winding equipment.

[0031] Step 3: Remove the rod and cut off any excess spring portion.

[0032] Please refer to this carefully. Figures 1-6The winding equipment includes a base 1, with a mounting frame 2 fixedly connected to one end of the base 1. A feeding roller 3 is rotatably connected to the outer wall of the mounting frame 2. A first support seat 4 and a second support seat 5 are fixedly connected to the top of the base 1. The base 1 winds the spring steel through a fixing mechanism 6 and guides the spring steel through a guiding mechanism 7. The fixing mechanism 6 includes a first rotating seat 601, which is rotatably connected to the inside of the first support seat 4. A second rotating seat 602 is rotatably connected to the inside of the second support seat 5. A motor 603 is mounted on the outer wall of the second support seat 5, and the output end of the motor 603 is connected to the second rotating seat 602. A second rotating block 604 is fixedly connected to the end of the second rotating seat 602 away from the motor 603. A first rotating block 605 is provided at one end of the first rotating seat 601. A limiting block 606 extending out of the first rotating seat 601 is slidably connected inside the first rotating seat 601. The limiting block 606 is fixedly connected to the first rotating block 605. A limiting spring 607 is connected between the limiting block 606 and the first rotating seat 601. A push frame 608 is fixedly connected to the end of the limiting block 606 away from the first rotating block 605. The push frame 608 extends out to the first rotating seat 601 and the first support seat 4. The fixing mechanism 6 also includes a connecting groove 609. The outer walls of the second rotating block 604 and the first rotating block 605 are both provided with connecting grooves 609. A positioning rod 610 is provided between the second rotating block 604 and the first rotating block 605. A connecting block 611 is fixedly connected to both ends of the positioning rod 610. A movable frame 612 is slidably connected inside the positioning rod 610 and the connecting block 611. The positioning rod 610 and the connecting block 611 extend out from both ends of the movable frame 612, respectively. A fixing ring 614 is fixedly connected to one end of the movable frame 612. A movable spring 613 is connected between the movable frame 612 and the positioning rod 610.

[0033] In this embodiment: one end of the spring steel is passed through the fixing ring 614, so that one end of the spring steel is connected to the positioning rod 610. After completion, the push frame 608 is pushed to move. The movement of the push frame 608 causes the limiting block 606 to move. The movement of the limiting block 606 causes the first rotating block 605 to move away from the second rotating block 604, which compresses the limiting spring 607. After completion, the positioning rod 610 is moved between the second rotating block 604 and the first rotating block 605. The push frame 608 is released. The first rotating block 605 is displaced by the elastic force of the limiting spring 607. The connecting block 611 enters the connecting groove 609, thereby installing the positioning rod 610.

[0034] As the connecting block 611 enters the connecting groove 609, the movable frame 612 contacts the inner wall of the connecting groove 609. The movable frame 612 moves under force, compressing the movable spring 613. The movement of the movable frame 612 drives the fixed ring 614 to move, and the fixed ring 614 clamps and fixes one end of the spring steel. When the connecting block 611 moves out of the connecting groove 609, the movable frame 612 is reset by the elastic force of the movable spring 613, thereby driving the fixed ring 614 to reset, thus automatically releasing the fixation of one end of the spring steel.

[0035] After completion, start motor 603. Motor 603 drives the first rotating seat 601 to rotate. The rotation of the first rotating seat 601 drives the first rotating block 605 to rotate. The rotation of the first rotating block 605 drives the positioning rod 610 to rotate, so that the spring steel is wound around the positioning rod 610.

[0036] Please refer to this carefully. Figures 1-4 The guiding mechanism 7 includes a rotating rod 701 and a guide rod 702. The rotating rod 701 and the guide rod 702 are rotatably connected to the inner cavity of the base 1. The rotating rod 701 is located below the first rotating seat 601, and the guide rod 702 is located on one side of the rotating rod 701. A sliding groove 710 is provided at the top of the base 1. A guide seat 708 is slidably connected to the inner wall of the sliding groove 710. A guide hole 709 is provided through the outer wall of the guide seat 708. A first synchronous wheel 703 is fixedly connected to the outer wall of the rotating rod 701. A first synchronous belt 704 is connected between the first rotating seat 601 and the first synchronous wheel 703. A second synchronous wheel 705 is fixedly connected to the outer wall of the rotating rod 701 on one side of the first synchronous wheel 703. A third synchronous wheel 706 is fixedly connected to the outer wall of the guide rod 702. A second synchronous belt 707 is connected between the second synchronous wheel 705 and the third synchronous wheel 706. The guide rod 702 passes through the guide seat 708.

[0037] In this embodiment: the spring steel passes through the feeding roller 3, through the guide hole 709, and is connected to the positioning rod 610. When the positioning rod 610 rotates, the first rotating seat 601 rotates synchronously. The rotation of the first rotating seat 601 drives the first synchronous wheel 703 to rotate through the first synchronous belt 704. The rotation of the first synchronous wheel 703 drives the rotating rod 701 to rotate. The rotation of the rotating rod 701 drives the second synchronous wheel 705 to rotate. The rotation of the second synchronous wheel 705 drives the third synchronous wheel 706 to rotate through the second synchronous belt 707. The rotation of the third synchronous wheel 706 drives the guide rod 702 to rotate. The rotation of the guide rod 702 drives the guide seat 708 to move, thereby making the spring steel automatically and evenly wound on the positioning rod 610.

[0038] Please refer to this carefully. Figure 4 and Figure 5The first rotating seat 601 has a displacement groove inside, which fits against the outer wall of the limiting block 606. The outer wall of the connecting block 611 fits against the inner wall of the connecting groove 609. The connecting block 611 is square in shape.

[0039] In this embodiment: the pusher 608 moves, causing the limiting block 606 to move. The limiting block 606 moves, causing the first rotating block 605 to move away from the second rotating block 604, which compresses the limiting spring 607. After completion, the positioning rod 610 is moved between the second rotating block 604 and the first rotating block 605. The pusher 608 is released, and the first rotating block 605 is displaced by the elastic force of the limiting spring 607. The connecting block 611 enters the connecting groove 609, thereby installing the positioning rod 610.

[0040] Please refer to this carefully. Figure 6 The movable frame 612 extends from the connecting block 611 at one end, which is provided with a bevel, and the fixing ring 614 is U-shaped.

[0041] In this embodiment: when the connecting block 611 enters the connecting groove 609, the movable frame 612 contacts the inner wall of the connecting groove 609. The movable frame 612 moves under force, which compresses the movable spring 613. The movement of the movable frame 612 drives the fixed ring 614 to move. The fixed ring 614 clamps and fixes one end of the spring steel. When the connecting block 611 moves out of the connecting groove 609, the movable frame 612 is reset by the elastic force of the movable spring 613, thereby driving the fixed ring 614 to reset, thus automatically releasing the fixation of one end of the spring steel.

[0042] Please refer to this carefully. Figures 2-4 The outer wall of the first rotating seat 601 and the first synchronous pulley 703 matches the inner wall texture of the first synchronous belt 704. The second synchronous pulley 705 and the third synchronous pulley 706 both match the second synchronous belt 707. The outer wall of the guide seat 708 is provided with a threaded hole, and the outer wall of the guide rod 702 is provided with a thread that matches the threaded hole.

[0043] In this embodiment: the first rotating seat 601 rotates synchronously, and the rotation of the first rotating seat 601 drives the first synchronous wheel 703 to rotate via the first synchronous belt 704. The rotation of the first synchronous wheel 703 drives the rotating rod 701 to rotate, and the rotation of the rotating rod 701 drives the second synchronous wheel 705 to rotate. The rotation of the second synchronous wheel 705 drives the third synchronous wheel 706 to rotate via the second synchronous belt 707. The rotation of the third synchronous wheel 706 drives the guide rod 702 to rotate, and the rotation of the guide rod 702 drives the guide seat 708 to move, thereby causing the spring steel to automatically and evenly wind onto the positioning rod 610.
